I’m not going to lie, this episode was a parade of insanity from start to finish, and it introduced more historical details than we probably needed to know. Even Wolf Watch host Jill Wagner kicked off the after-show by saying, “What’s going on with Stiles? I don’t know!”

(Gee, thanks for the help, Aunt Kate.)

HER-STORY LESSON | For starters, did you know Kira’s mom is actually 900 years old? She casually dropped that fact onto her daughter during a story about her experience at an Oak Creek internment camp in 1943 — which did exist, despite what the kiddos were previously told. Anyway, Kira’s mom had herself a handsome soldier boyfriend, with whom she uncovered the administration’s massive conspiracy to sell medicine on the black market, leaving the prisoners to die. Bringing this to her fellow prisoners’ attention led to a massive riot, which incited a bitten werewolf named Satomi.

BIRTH OF EVIL | In the midst of the chaos, Kira’s mom’s boyfriend Reese was badly burned and brought to the brink of death. Fed up with all that noise, she summoned the Nogitsune to take over her body and make her enemies pay — only it didn’t possess her; it possessed Reese! With Satomi by her side and the Katana in hand, Kira’s mom defeated Reese and disposed of the body, though not very efficiently. She also buried the now-iconic fly under the Nemeton, so it’s kind of Scott’s pack’s fault that all these evil spirits have returned in the first place.

HAKUNA KATANA | Thanks to Kira’s mighty Pikachu Thunder Kitsune powers, she was able to piece the Katana back together — and damn, does she know how to wield that thing! Unfortunately, she intends to use it to defeat Stiles, just as her mom used it to defeat Reese back in 1943. (And we all know how well that turned out.)

ALLISON’S FAILING ECON?! | Considering everything she’s been through this season — or, at least, what her friends have been through — I’d say Allison was long overdue for an emotional breakdown. It finally came this week during an elevator ride with Sheriff Stilinski, who was more than happy to lend a sympathetic ear as she ranted about everything going wrong in her life: Isaac possibly dying, not knowing where she stands with Scott, and of course, the fact that she’s failing econ. (Honestly, I’m just stunned someone actually referenced schoolwork on this show.)

CHECKMATE | The very idea of Stiles playing chess boggles my mind — he seems like more of a checkers kinda guy — but lo and behold, the chess board we saw in his room tonight could bear serious significance in the fight against the Nogitsune. (As for Derek being the king piece on Stiles’ board, I think we can all agree that Teen Wolf is toying with Sterek shippers’ emotions yet again.)

Teen Wolf fans, is your brain still functioning after this week’s info-heavy episode? And do you think Scott will ever get on board with Operation: Stab Stiles? Drop a comment with your thoughts/confusion below.
